抄録

Characteristic of palatinose-hydrolyzing activity was studied in the sucrase-isomaltase complex purified from adult rat intestine.<BR>1) Palatinose-hydrolyzing activity (specific activity) was increased by purification of sucrase-iso-maltase complex in parallel with sucrase and isomaltase activity.<BR>2) Palatinose was hydrolyzed in competition with isomaltose by sucrase-isomaltase complex.<BR>3) Palatinose-hydrolyzing activity, like isomaltase activity, was not inhibited by α-glucosidase inhibitor, acarbose, which inhibits sucrase and maltase activity.<BR>Therefore, we concluded that palatinose is hydrolyzed by the active site of isomaltase of sucrase-isomaltase complex.
